Port the app to a multi-platform framework so iPhone users would be covered as well

Flutter has ARCore plugin ( https://github.com/giandifra/arcore_flutter_plugin/tree/master/example , https://pub.dev/packages/arcore_flutter_plugin ), but I'll need to research if all the required Sceneform features are covered.

If Flutter cannot support what we are doing then research if Unity can do it.

Extra: Terry Solis asked me: why I wouldn't consider Ionic. We have HTML5 based AR / WebVR / WebGL / Three.js solution, or more native (hybrid) Ionic with ARCore / ARKit. Article: https://www.joshmorony.com/augmented-reality-in-an-ionic-angular-pwa/
